advantages thereof will fully appear upon consideration of the following descriptionin conjunction with the accompanying drawings forming part of this specification, and of which:

Fig. 1 is a perspective view of a refrigerator cabinet embodying the invention;

Fig. 2 is a vertical section of the refrigerator;

Fig. 3 is a horizontal section taken on line 3-3 in Fig. 2; and

Fig. 4 is a rear view of the refrigerator. Referring to Fig. 1, a refrigerator cabinet l0 provides a thermally insulated storage compartment accessible by means of a door l2. The

cabinet includes a front frame l3 constructed |3 by screws 20. The liner i8, which forms the storage compartment i|,-may be coated on the inside with porcelain enamel, as well known, and is provided in the rear with an opening, which may be referred to as a liner opening, surrounded by a wood frame 2| through which the cooling element 22 of a refrigerating apparatus may be inserted. To the liner opening frame 2| and the front frame |3 are secured a plurality of' insulating members 23 consisting of corrugated cardboard sheets faced with metalfoil, in spaced relation to each other and parallel to the liner it. The sheets 23 are provided with flanges '31 and may be secured to the liner opening frame 2| and the front frame l3 by nails or other fastening means. It will be understoodthat the frames may be constructed of other material than wood, and other types of insulation may be employed.

The rear portion of the cabinet consists of upright corner posts 24 and 25 joined by a cross member 26, of steel or wood, at approximately the level of the front cross member To the inside 'of the rear corner posts 24 and 25 are secured, for example, by screws 21, the side edges 23 and 29 ermany October 5, 1934 of a generally U-shaped metal plate, extending from the top of the posts 24 and 25 to approximately the level of the front cross member H. The plate 3|) forms the supportingstructure for a refrigerating apparatus 3| the cooling element 22 of which is adapted to be disposed within the storage compartment The front section of the cabinet including the frame l3, the liner I8 and insulation members 23, and the rear section including the corner posts 24, 25, the plate 30 and the refrigerating apparatus 3|, are telescoped together by inserting the cooling element 22 through the liner opening frame -2| into the storage compartment forming a double cantilever arrangement whereby both sections are mutually supporting. The plate 30 is provided with a block of insulation material 32 which is disposed within the liner opening frame 2|. The liner. opening is sealed on the inside by a liner opening trim member 33. p

The outer wall or casing 34 of the cabinet consists of an inverted U-shaped sheet of metal, which isgiven any desired finish, and which is placed over the rounded frame l3 and rear cor-" ner posts 24 and 25 and extends downwardly on each side to the cross member I]. The casing 34 is secured by nails or screws to the wooden frame and corner posts. The top rear portion of the casing or cover 34 is cut out and provided with a downward flange 35 which is secured to the.

plate 30 by means of metal screws. The cut-out is provided to permit good air circulation at the back of the cabinet for air cooling of the refrigerating apparatus 3|. A flanged bottom plate 36, secured to the sides of the cover 34 along its lower edges, to the front frame 4 3, and to the plate 30, serves to reinforce the structure.

Various changes may be made within the scope of my invention as indicated by the following claims.

What is claimed is: v 1. Refrigerator including a cabinet having a front frame, a storage compartment secured to said frame, and rear corner posts, a refrigerating apparatus supported by said posts, and an outer casing joining said frame and rear cornerposts.

2. Refrigerator including a cabinet having a. front frame, a storage compartment secured to said frame, insulation secured to said frame, and rear corner posts, a refrigerating apparatus supported by said posts, and an outer casing joining said frame and rear corner posts.

3. Refrigerator including a cabinet having a front frame, a storage compartment secured to said frame, insulation secured to said frame, and

, the refrigerator.

ported by said posts, and a unitary casing joining said frame and rear corner posts and forming the sides and top of said cabinet.

4. Refrigerator including a cabinet having a front frame, a storage compartment secured to said frame, insulation comprising spaced metal sheets and secured to said frame, and rear corner posts, a refrigerating apparatus supported by said posts, and a unitary outer casing joining said frame and rear corner posts and forming the sides and top of said cabinet.

5. Refrigerator including a cabinet having a wooden front frame, a storage compartment screwed to said frame, insulation comprising, corrugated cardboard sheets covered with metal foil nailed to said frame, and wooden rear corner posts, a refrigerating apparatus supported by said posts, an outer casing screwed or nailed to said frame and rear corner posts the upper portion of said frame forming thedoor opening and the lower portion of said frame and corner posts forming the legs of said cabinet 6. Refrigerator including a front frame and a storage compartment secured thereto, a rear frame and refrigerating apparatus secured thereto, said'parts being arranged to form a double cantilever, and an outer casing joining said frames. 1

'7. Method of constructing a refrigerator comprising forming a front frame, storage compartment and insulation as a unit, forming a rear frame and refrigerating apparatus as a unit, bringing said units together in a double cantilever arrangement, and securing said frames together by a casing forming the sides and top of 8. Method of constructing a refrigerator comprising forming a front frame, storage compart- .ment and insulation as a unit, forming a rear frame and refrigerating :apparatus as a unit, bringing said units together in a double cantilever arrangement, securing said frames together by a casing forming the sides and top of the refrigerator, and reinforcing the whole by securing a horizontal plate to said frames and casing immediately beneath said storage compartment. 1
